NOTE: this is continuously being re-uploaded as i modify the design (which is very much in WIP) so make sure you come here often. This is the Re-Design of the LM10UU 10mm XRods variation (http://www.thingiverse.com/thing:1606042), this time with the SF-1 1012 Self-Lubricating Bushings. It is designed for Bowden setups and Horizontal Rods, getting rid of most of the static and dynamic errors that affect printing during the accelerations/jerks/etc of a 3D printer (discussion here: http://forums.reprap.org/read.php?1,668254). Sketchfab 3D model with exploded view here: https://skfb.ly/OYpF DETAILS: X uses 10mm rods and SF-1 1012 Bushings Y uses 10mm rods and SF-1 1012 Bushings belt is gt2 Hotend is a clone of E3Dv6 axial fans are 30mm radial blowers are 4020 type all in all the XCarriage is very symmetrical and any forces applied during accelerations, jerks, etc, are evenly distributed so that the nozzle remains as fixed as possible. CHANGES from the LM10UU variant: SF-1 1012 instead of LM10UU YCarriage Re-Design XCarriage Base is the same length (72.75mm) Hotend mount is a bit more modular (belt catchers are printed separately), the Axial Fans are more engled to better cool the lower fins of the hotend and there is now a supplementary fin that directs the air from the axial fans towards the lower fins with preference NOTE: I kept the XCarriage Base Part the same dimmensions as the LM10UU one so that the HotendMount is compatible. Features: 72.75mm XCarriage (the Belt-Catchers go inside the YCarriages so they are not wasted space); Belts go in straight line and in the same plane from YCarriages towards the XCarriage; Belts can be tensioned with simple screws and dome-nuts pressing on the belt, forcing it into the niche designed for it; belts can be independently tensioned; Hotend supported both upside carriage and lower side by the 4 screws; Dual-30mm fans for coldend cooling; Dual-30mmfan (or squirrelcage blowers) for part cooling [still very undecided here]; TBD: 1) even more simplification (looks rather complicated, albeit printable) 2) design it for dual hotend [...] Cheers, Flo.
